There are persistent rumours of large black cats in Australia but none have ever been caught by anyone who couldn't be described as a red neck who describe them as panther sized black cats. The Aboriginals also have long rumours of them. If cats managed to catch a ride here 10,000+ years ago, would they evolve to the point where their natural isolation from each other would make them undetectable to modern biologists?

Barndad:Jaguarundi are mainly South and Central American but there are some feral animals meant to be found in Florida.

We have some around the Galveston Bay area. I suppose what I meant to ask is the range of a single jaguarundi. I am curious how far the animals I have encountered might have traveled. We know they were jaguarundi as they have a peculiar way of skinning their prey.

basemetal:I know some credible people that have seen black cougars/panthers in the south canadian river area in Oklahoma, yet every game warden and biologist says there is no way. Are the authorities wrong?

People say that in the Panhandle all the time (including my wife, smh), despite their being little evidence of melanism among felis concolor, let alone evidence of Florida panthers being in the panhandle.
